FRAME FOR MULTIPLE-FAME WINDOW SASHES Filed July 1a, 1946 Patented Apr.4, 1950 OFFICE SASHES FRAME FOR MULTIPLE-PANE WINDOW Raphael Lemyre,Sore], Quebec, Canada In. Canada July '26, 1945 Application July 13,1946, Serial No. 683,535

1' Y The present invention pertains toa novel frame for multiple-pane.window' sashes- The principal object of the .inventionis. to provide aframe that seals and insulatesthe spaces between the panes so that it isno longernecess'ary to provide a twopart or dualsash in order; to obtainan enclosed insulating space. I

Another object of theinvention is to provide a:sealed sash ofthecharacter described which is especially suitable. for any kind ofvehicle such as railroad cars, airplanes, motorcars, dirigibles, etc.,and the like toinsure good visibility regardless of temperaturevariations on both sides of the window. Another object of the inventionis to provide a frame that holds a plurality of panes of glass or:transparent plastic material with an airtight seal. Still another objectof the invention is to provide a frame for multiple panes of thecharacter described in which it isnecessary to clean only 6 Claims. (01.20 56.5).

the outer surfaces of the respective panes due to the fact that theinner surfaces are protected from accumulation of dirt thereon.

Still another object ofthe invention is to provide a device of thecharacter described which is simple and inexpensive in construction andeasily assembled. I 1

In theaccomplishment of these objects, the invention comprises a singleframe in which severalpanes are mounted. A tight seal for the space orspaces between the panes is formed by inserting the edges of the panesfirst in relatively solidresilient strips of naturalrubber, syntheticrubber or equivalent material. In order'to seal the spaces, .a means isprovided for clampingthe resilient strips on their sides and thusagainst the individual panes. I

The last named means isincorporated in the moulding strips engaging thelateral surfaces of the resilient strips. Outward of the resilientstrips, the binding strips are spaced apart and are formed withoutwardly diverging inner surfaces. Between each pair of opposedmoulding strips is inserted'a bind-ing strip with its longitudinal edgesrounded and the moulding strips pivotally mounted thereon. A wedgeinserted between the opposed moulding strips can be adjusted torock'thelatter onthe intervening binding strips, thereby compressing themoulding strips in the inserted resilient strips and-sealing the-lattertightly against the panes. The wedge is'in theform of achannel-havingoutward or inward diverging sides and is attached by screws to thecorresponding binding strip. The described clamping action on theresilient strips is obtained by tightening the screws.

because of the tight seal, Consequently, only the outer surfaces needbe. washed If insuificient, in particular cases, a, thinmetal sheetcould cover the rubber strip between the window panes.

The invention is fully disclosed by way of example in the followingdescription and. in the.

accompanying drawingsin which:

Figure 1 is a cross section of a sash frame for multiple window. panes;

FigureZ is a detail elevation. thereof, partly. broken away;

Figure 3 is a perspective View of a corner;

Figure 41s a section similar to Figure 1,. showing also the stationaryframe;

Figure 5 is a section on the line5+-5 of.Figure, 3, and

Figure 6 is a section of a modified construction.

Reference to these views will now. be made by use of like characterswhich areemployed to. designate corresponding parts throughout.

In Figures 1, 2 and 4 are shown two panes I spaced apart and havingtheir: edges received in grooves or slots 2 formed in asurroundingstrip.

sections, assuming that the panes are quadrilateral; and the corners aremiteredas shown in Figures 2 and 3.- The longitudinal outer edges. ofthestrips tare rabbetedat 4, and the ad.-

J'acent-mouldingfstrips 5 at opposite sides of the strips 3 are formedwith ribs 5:: received in. the grooves. 4. I

Abinding strip fi is laid. between the members 5 in engagement with theouter. transverse surface of each-strips. The edgess'lof the members 6;are rounded and received in correspondingly shaped grooves l. inithestripsfi. Themember 6 unites the adjacent moulding strips5fand serves asa pivotal support for them for a purpose that will presently bedescribed. I

outwardly of the members 6 the strips iare bevelled at- 8. on theirinner surfaces so that the:

opposite surfaces diverge. outwardly. The 013-- posed surfaces are.engaged :by the inclined-flanges. 9 of aninserted ueshapediwedge memberIt). At-

as the strips rock on the ends of the members '6 as set forth above. Theinner edges of the members 5 are compressed against the sides of therespective strips 3, thereby forming tight seals around the edges of thepanes 1. Because of the tightness, there is obtained an air tightinsulating space between the panes I, and this space may be filled withan insulating gas if desired.

The structure thus far described is enclosed in a frame, as shown inFigure 4, consisting of a pair of side members [2 united at a suitablelap joint I3 and secured by screws or nails. l4. The'ends of the strips5 are mitered as shown in Figure 2 except at the extreme outer cornerswhere they are cut and fitted on a joint line [5 parallel to one of theouter edges and fastened together by a dowel I6 as shown in Figures 2and 3. Screws I! are .passed through the frame members 12 into thestrips 5, and the inner surfaces of the members -|2 are flared slightlyoutwardly at 18 to permit the aforementioned rocking movement of themembers 5.

In the modification shown in Figure 6 the resilient strips 3' are widerthan shown in Figures 1 and 4 and are formed with four grooves 2' toreceive the edges of .four panes I. The binding strip '6' and thespreader ID are likewise wider in order to engage the lateral strips *5.

Although specific embodiments of the invention have been illustrated anddescribed, it will beunderstood that various alterations in the detailsof construction may be made without departing from the scope of theinvention as indi cated by the appended claims.
